When7 thecunit. I IIJ/is` constructed oficementthe walls' thereof are prferably.reerforcdl by metal wire or'bars`22.

Certain of .the curb and sewer units I l) are protrated my invention in use along opposite sides of a concrete aireld runway A, the bottom of the units resting upon the sub-grade B. The units are connected together in end to end relation and parallel the sides of the runway A with their top y surfaces flush with the runway A. The gratings I2 close the open tops of the bodies of the units and seat upon the shoulders I9--I9. Each grating I2 is formed of concrete or other plastic material and comprises an elongated slab-like body 25 having spaced drain openings 26 therein. The grating is of a length equal to that of the body I I on which it fits, the ends of the slab body terminating in reduced offset flanges 2'I and 28. When in position, the ange 23 of one grating overlies the ange 21,of the nextI adjacent unit whereby to provide a lapping joint between the ends of adjacent gratings. Water which may drain from the runway A to oppositesides thereof will flow onto the gratings I2 and pass through the drain openings 26 into the passageway I8, from where it ows to a main sewer or-pass out through the sub-surface drain openings 23 into the subgrade B. f

In Figures 5, 6 and 7,1 have illustrated my invention as being installed along the sides of a street or roadway C, wherein the upper portions of the bodies of the units I rise above the adjacent surface level thereof to form a curb. The drain inlets 24 are flush with the adjacent surface level of the roadway to receive water which may drain Itherefrom, said water entering the passageway I8 and being carried away to a main sewer or for escape through the sub-surface drainage openings 23. In this use, the grating sections I2 may be usedas a-walk for persons walking along the roadway.

' In Figure 8 of the drawings, I have illustrated a slight modified form of my invention, wherein one end of the top of the body II is closed as at 29. The closed end of one `unit fits against the top open end of a next adjacent unit to form a rectangular opening 39 for receiving a similar shaped grating 3l.

AIn Figure 9 of the drawings, there is illustrated a furher modiication in which both ends of the open ton of the body II of each unit is closed as `at 35--35 to provide a rectangular shaped opening 33 for receiving a simi-lar shaped grating l(not shown). A

.When the units are employed along the sides of roadways, the gratings may bein the form of solid covers to provide a smooth surface on which to Walk.

In Figure there is illustrated a still further modified form in which the bodies of the units II are similar to thcseshow in Figure 1, but in which solid covers or slabs 36 cover the open top thereof. The end of each slab 39 is formed with a notch 31 and when the notches of two adjacent slabs are in complementary confronting relation to each other, a drain opening 38 is formed through 4 which water may drain into the passageway I 8.

When the units II are laid'end to end on a grade in the direction of the intended ilow of Water therethrough, it will be understood that the passageways I8 are self cleaned for any solids will be washed away with the drain water for there are no corners along the passageway in which solids may be trapped. Should manual cleaningbe necessary, the covers or gratings are removed from the tops ofthe bodies I I, thus permitting free'access to the passageway I8.

Due to the ovate shape of the body II of the unit, the same may be easily handled by rolling the same which expedites the transportation of the units and the placing of the same in position for use.

While `Iihave shown and described what I consider to be the most practical embodiments of my'invention, I wish it to be understood that such changes in construction, design and materials as come within the appended claims may be resorted to if desired without departing from the spirit of the invention. t

Having .thus described the invention, what I claim as new and desire to secure by Letters Patent is:

1. A combined curb and drain comprising a reenforced concrete elongated hollow body of horseshoe shape in cross section having a rounded inner bottom wall and curved upwardly converging opposed side walls, one of said side walls having an inwardly inclined drain inlet therein above the bottom wall thereof, opposed parallel ledges provided on the inner sides of the side walls adjacent the top thereof, and a slab-like concrete grating seated on the ledges and closing the top of said body and disposed flush with the top thereof, the body also having drain openings from the interior adjacent the bottom and additional inlets in its top.

2. A combined curb and drain unit comprising a rigid elongated body of concrete or like plastic material beingovate shape in cross section having flat top and bottom surfaces, said body having a i'low passage therein extending lengthwise thereof from end to end, the inner surface of the bottom of the iiow passage being curved on an arc struck ironia single axis, one of the side walls of the said body abovethe bottom of the passage having inlet surface drain openings therein, said body also having subsurface outlet openings leading outwardly and downwardly adjacent the bottom of said passage.
